I was excited about the hiring of Miller as OL coach last year. I agree that it was too early to judge some of them, but I had issues with Jay Johnson and the play calling all year.
Johnson gave up on the run too frequently, and Shannon Brooks did not get enough carries once he recovered from his foot injury. Jay Johnson might have ended up as a great OC, but I saw a lot last year I did not like, including the Wisconsin game and the decision to have Mitch drop back and throw with 20 seconds left in the half vs. Purdue (-7). I thought the Limegrover team, once freed from Jerry Kill was better than what Jay Johnson came up with.
I hope the new guy is able to get everything possible out of Smith and Brooks next year. Maybe even #2 Gentry or the other remaining WR hype guy will appear from the netherworld and remind us all of Randy Moss and Terrell Owens.
